Yaël Dayan (Hebrew: יעל דיין‎‎, born 12 February 1939) is an Israeli politician and author. She served as a member of the Knesset between 1992 and 2003, and from 2008 to 2013 was the chair of Tel Aviv city council.[1] Her service on the city council ended with the 2013 election.[2] She is the daughter of Moshe Dayan and sister of Assi Dayan.

In 1992, Dayan was elected to the Knesset on the Labor Party list and served as chairwoman of the Committee on the Status of Women. She was instrumental in pushing forward Israel's sexual harassment law in the 1990s. Re-elected in 1996 and 1999 (as a member of One Israel, an alliance of Labor, Meimad and Gesher), Dayan became chairwoman of the Committee on the Status of Women for a second time in 1999.

She lost her seat in the 2003 elections, and left Labor to join Meretz with Yossi Beilin. Dayan headed the Meretz list in the Tel Aviv municipal elections in 2004, with the party winning 5 out of 31 Seats on council and joining Ron Huldai's coalition. Until 2008 she served as Deputy Mayor and until 2013 she was responsible for social services. Mayor Huldai chose not to include Dayan on his list of candidates for the 2013 election, effectively ending her political career.
